"Another tall story from Orcon's marketing dept…"

Orcon said the app allows Kiwis to take their home phones anywhere - bringing down the cost of national and international calling.

Yet after downloading the app immediately after the launch, an enthusiastic user was quickly put off.

"I was with orcon for little over a year and apart from the massive missed calls or when people ring me, it say no such number, and discounting, there help desk and service and billing was also a joke, I am glad that I have swapped over to flip."

"Come on Vodafone, Telecom, 2D, time to start providing 'data only' mobile deals, with large enough Caps to allow mobile VoIP calling/messaging using the popular services. How long are you going to hold out?"
